2011-10-06cleanup: use internal memory allocation wrapper functions everywhereLibravatar Brandon Casey2-2/+2
The "x"-prefixed versions of strdup, malloc, etc. will check whether the allocation was successful and terminate the process otherwise. A few uses of malloc were left alone since they already implemented a graceful path of failure or were in a quasi external library like xdiff. Additionally, the call to malloc in compat/win32/syslog.c was not modified since the syslog() implemented there is a die handler and a call to the x-wrappers within a die handler could result in recursion should memory allocation fail. This will have to be addressed separately. Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-06-20cygwin: trust executable bit by defaultLibravatar Junio C Hamano1-1/+1
Earlier 7974843 (compat/cygwin.c: make runtime detection of lstat/stat lessor impact, 2008-10-23) fixed the low-level "do we use cygwin specific hacks for stat/lstat?" logic not to call into git_default_config() from random codepaths that are typically very late in the program, to prevent the call from potentially overwriting other variables that are initialized from the configuration. However, it forgot that on Cygwin, trust-executable-bit should default to true. Noticed by J6t, confirmed by Ramsay Jones, and the brown paper bag is on Gitster's head.

2011-06-16t1301-*.sh: Fix the 'forced modes' test on cygwinLibravatar Ramsay Jones1-2/+1
The 'forced modes' test fails on cygwin because the post-update hook loses it's executable bit when copied from the templates directory by git-init. The template loses it's executable bit because the lstat() function resolves to the "native Win32 API" implementation. This call to lstat() happens after git-init has set the "git_dir" (so has_git_dir() returns true), but before the configuration has been fully initialised. At this point git_config() does not find any config files to parse and returns 0. Unfortunately, the code used to determine the cygwin l/stat() function bindings did not check the return from git_config() and assumed that the config was complete and accessible once "git_dir" was set. In order to fix the test, we simply change the binding code to test the return value from git_config(), to ensure that it actually had config values to read, before determining the requested binding.

2011-06-06Windows: teach getenv to do a case-sensitive searchLibravatar Johannes Sixt1-3/+20
getenv() on Windows looks up environment variables in a case-insensitive manner. Even though all documentations claim that the environment is case-insensitive, it is possible for applications to pass an environment to child processes that has variables that differ only in case. Bash on Windows does this, for example, and sh-i18n--envsubst depends on this behavior. With this patch environment variables are first looked up in a case-sensitive manner; only if this finds nothing, the system's getenv() is used as a fallback.

2011-06-06mingw.c: move definition of mingw_getenv downLibravatar Johannes Sixt1-15/+15
We want to use static lookup_env() in a subsequent change. At first sight, this change looks innocent. But it is not due to the #undef getenv. There is one caller of getenv between the old location and the new location whose behavior could change. But as can be seen from the defintion of mingw_getenv, the behavior for this caller does not change substantially. To ensure consistent behavior in the future, change all getenv callers in mingw.c to use mingw_getenv. With this patch, this is not a big deal, yet, but with the subsequent change, where we teach getenv to do a case-sensitive lookup, the behavior of all call sites is changed.

This assumption does not hold true for the code-path from prefix_path (on Windows), where real_path can be called before normalize_path_copy. Fix real_path so it doesn't make this assumption.

Somebody tried to compile fnmatch.c compatibility file on Interix and got an error because no header included in the file on that platform defined NULL. It usually comes from stddef.h and indirectly from other headers like string.h, unistd.h, stdio.h, stdlib.h, etc., but with the way we compile this file from our Makefile, inclusion of the header files that are expected to define NULL in fnmatch.c do not happen because they are protected with "#ifdef STDC_HEADERS", etc. which we do not pass.

Even though Windows's socket functions look like their POSIX counter parts, they do not operate on file descriptors, but on "socket objects".

va_copy is C99. We have avoided using va_copy many times in the past, which has led to a bunch of cut-and-paste. From everything I found searching the web, implementations have historically either provided va_copy or just let your code assume that simple assignment of worked.

2011-02-07mingw: make failures to unlink or move raise a questionLibravatar Heiko Voigt1-0/+78
On Windows in case a program is accessing a file unlink or move operations may fail. To give the user a chance to correct this we simply wait until the user asks us to retry or fail. This is useful because of the following use case which seem to happen rarely but when it does it is a mess: After making some changes the user realizes that he was on the incorrect branch. When trying to change the branch some file is still in use by some other process and git stops in the middle of changing branches. Now the user has lots of files with changes mixed with his own. This is especially confusing on repositories that contain lots of files. Although the recent implementation of automatic retry makes this scenario much more unlikely lets provide a fallback as a last resort. Thanks to Albert Dvornik for disabling the question if users can't see it. If the stdout of the command is connected to a terminal but the stderr has been redirected, the odds are good that the user can't see any question we print out to stderr. This will result in a "mysterious hang" while the app is waiting for user input. It seems better to be conservative, and avoid asking for input whenever the stderr is not a terminal, just like we do for stdin.

Commit c03c831 (do not depend on signed integer overflow, 05-10-2010) provokes an msvc build failure. The cause of the failure is a missing definition of the INTMAX_MAX constant, used in the new maximum_signed_value_of_type(a) macro, which would normally be defined in the C99 <stdint.h> header file. In order the fix the compilation error, we add an appropriate definition of the INTMAX_MAX constant, along with INTMAX_MIN and UINTMAX_MAX, to an msvc compat header file.

2010-11-23win32: use our own dirent.hLibravatar Erik Faye-Lund6-269/+132
The mingw-runtime implemenation of opendir, readdir and closedir sets errno to 0 on success, something that POSIX explicitly forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be read due to EMFILE") introduce a dependency on this behaviour, leading to a broken "git clone" on Windows. compat/mingw.c contains an implementation of readdir, and compat/msvc.c contains implementations of opendir and closedir. Move these to compat/win32/dirent.[ch], and change to our own DIR structure at the same time. This provides a generic Win32-implementation of opendir, readdir and closedir which works on both MinGW and MSVC and does not reset errno, and as a result git clone is working again on Windows.

The Windows port have so far been using process handles in place of PID. However, this is not work consistent with what getpid returns. PIDs are system-global identifiers, but process handles are local to a process. Using PIDs instead of process handles allows, for instance, a user to kill a hung process with the Task Manager, something that would have been impossible with process handles. Change the code to use the real PID, and use OpenProcess to get a process-handle. Store the PID and the process handle in a linked list protected by a critical section, so we can safely close the process handle later. Linked list code written by Pat Thoyts.
